Abstract:We investigate the fueling and the feedback of nuclear activity in the Seyfert 2 galaxy NGC1068, by studying the distribution and kinematics of molecular gas in the torus and its connections. We use ALMA to image the emission of a set of molecular gas tracers in the circumnuclear disk (CND) and the torus of the galaxy using the CO(2-1), CO(3-2) and HCO^+^(4-3) lines with spatial resolutions ~0.03"-0.09"(2-6pc). ALMA resolves the CND as an asymmetric ringed disk of D~400pc-size and mass of ~1.4x10^8^M_{sun}_. The inner edge of the ring is associated with edge-brightened arcs of NIR polarized emission identified with the working surface of the AGN ionized wind. ALMA proves the existence of a molecular torus of M_torus ...(more)

The velocity-integrated intensity maps obtained in the CO(2-1), CO(3-2), and HCO^+^(4-3) molecular lines in the Seyfert 2 galaxy NGC1068 (M77) by the Atacama Large Millimeter Array (ALMA). The interferometric observations were carried out between October 2016 and September 2017. The datasets presented here were imaged with synthesised beams of 0.11"x0.068"@PA=80{deg} for the CO(2-1) line, 0.13"x0.065"@PA=100{deg} for the CO(3-2) line, and 0.081"x0.046"@PA=78{deg} for the HCO+(4-3) line. The images are in FITS-format. The intensity scale is in Jy.km/s/beam and has been corrected by the Primary Beam attenuation at each frequency. See the paper for further details.
